Fire Resistant High Alumina Bricks Kiln Alumina Refractory Brick For Furance
Description
Fire-resistant high alumina bricks are commonly used in furnaces and high-temperature industrial applications. They are specifically designed to withstand extreme heat conditions and provide excellent thermal insulation.
Fire-resistant high alumina bricks can withstand temperatures ranging from 1500°C to 1800°C, making them ideal for use in furnaces that operate at extremely high temperatures.
These bricks have low thermal conductivity, which minimizes heat transfer through the brick lining. This property helps to conserve energy and maintain a stable temperature within the furnace.
